Insider Trading and the PIT Regulations
What SEBI's Prohibition of Insider Trading rules actually require, who counts as an insider, and how the legal insider-trade disclosures become a usable signal.
'Insider trading' has two very different meanings, and conflating them is where confusion starts. One is the crime: trading on unpublished price-sensitive information. The other is the legal, disclosed activity: company insiders buying or selling their own stock through proper channels, which SEBI requires them to report — and which is genuinely useful to read.
This chapter covers SEBI's Prohibition of Insider Trading (PIT) Regulations, 2015, and how the legal disclosures become a signal.
What the PIT rules prohibit
The core prohibition: no one may trade in a security while in possession of Unpublished Price-Sensitive Information (UPSI) — material, non-public information that would affect the price (earnings, M&A, large orders, regulatory actions). The rules also bar passing UPSI to others ('tipping') except for legitimate purposes.
Designated persons — promoters, directors, KMP (CEO, CFO, Company Secretary) and other employees with UPSI access — face the strictest controls, including their immediate relatives.
Trading windows and disclosures
Trading window closure: companies close the trading window for designated persons when they could reasonably hold UPSI — most visibly in the run-up to results — so insiders simply can't trade then.
Continual disclosure: when a promoter, director or designated person's trades aggregate to more than Rs 10 lakh in value over a calendar quarter, they must disclose to the company within two trading days, and the company reports it to the exchange. This is the legal, public insider-trade trail.
Trading plans let insiders pre-schedule trades well in advance (after a cooling-off period) so they can transact without it looking opportunistic — useful context when you see a disclosed insider trade.
Reading legal insider trades as a signal
Open-market buying by insiders is the higher-conviction signal. Insiders sell for many reasons — diversification, tax, personal liquidity — but they typically buy their own stock in the open market for one reason: they think it's cheap. Cluster buying by several insiders is stronger still.
Context matters. A sale under a pre-disclosed trading plan is mechanical, not a view. A discretionary sale right before a quiet period is worth more attention. And ESOP-related transactions aren't directional signals at all.
Common misreads
- Reading every insider sale as bearish — most sells are diversification, tax or pre-planned trading-plan trades.
- Confusing the crime (trading on UPSI) with legal, disclosed insider trades — the disclosures are the usable part.
- Treating ESOP allotments/exercises as directional buying — they aren't a conviction signal.
Key takeaways
- PIT 2015 prohibits trading on UPSI (material non-public info) and tipping it to others.
- Designated persons = promoters, directors, KMP and employees with UPSI access (plus immediate relatives).
- Trading window is closed for insiders when they may hold UPSI (e.g. before results).
- Continual disclosure: trades aggregating > Rs 10 lakh/quarter disclosed within 2 trading days.
- Open-market insider BUYING is the higher-conviction signal; selling has many benign reasons.
Insider trading rules and signals
What is UPSI?
Unpublished Price-Sensitive Information — material information about a company that isn't public yet and would likely move the price if it were: financial results, mergers and acquisitions, large contract wins or losses, dividend changes, regulatory actions. Trading while in possession of UPSI is what the PIT regulations prohibit.
When must insiders disclose their trades?
Under the continual-disclosure rule, when a promoter, director or designated person's trades aggregate to more than Rs 10 lakh in value within a calendar quarter, they must report to the company within two trading days, and the company forwards it to the exchange. That creates the public, legal record of insider activity you can read.
Why is insider buying a stronger signal than insider selling?
Because insiders sell for many reasons unrelated to their view — diversification, tax, buying a house, pre-scheduled trading plans, ESOP mechanics. They generally buy their own stock in the open market for one reason: they believe it's undervalued. So an open-market insider buy, especially a cluster of them, carries more information than a sale.
What is the trading window closure?
A period when designated persons (insiders) are barred from trading their company's stock because they could reasonably be expected to hold UPSI — most commonly the weeks before results are announced. SEBI has even pushed frameworks to freeze designated persons' PANs at the security level during closure to enforce it.
Does a disclosed insider trade mean something is about to happen?
Not necessarily. Insiders can't legally trade on UPSI, and many trades are routine or pre-planned. Read disclosed insider trades as a sentiment input — especially open-market buying — rather than as a leak of impending news, which would itself be illegal.
